RTC INT and SVC are not work when APP is not at offset 0x1C000 with S113

nrf_bootloader_app_start sets the app_start address which seems to be working for your app as you confirmed that the main function is started in the app even after your moved the app_start offset.

Did nrf_dfu_mbr_irq_forward_address_set  return without any errors? It does not look like this function has done what it is supposed to do after successful complettion.

Hi, 

I can reproduce the same issue with S132 secure DFU bootloader w/o moving APP (NRF SDK example). 
What I changed is only change "start_addr" in nrf_bootloader_app_start() and nrf_dfu_mbr_irq_forward_address_set() from MBR_SIZE to 0x26000  (which is the default APP offset if apply S132).

The symptom is APP is stocked at 0x000263D2 (SVC_Handler) when call nrf_sdh_enable_request(), and never returned, and there is no error returned from nrf_dfu_mbr_irq_forward_address_set() in bootloader.

You need to use an MBR command for sd init after you have reached the application

sd_mbr_command_t command =
    {
        .command = SD_MBR_COMMAND_INIT_SD
    };
    ret_val = sd_mbr_command(&command);
